IMPROVEMENT IN PIPE-ORGAN VALVES.

Specification forming part of Letters Patent No. 145.453, dated December9,1873 application filed June 20, 1873.

To all whom it may concern:

Be it known that I, WILLIAM ScnULKn, of Hamilton, in the county ofButler and in the State of Ohio, have invented certain new and usefulImprovements in Pipe-Organs; and do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccom rianying drawing making a part of this specification, in whichFigure 1 is a section of a wind-chest upon a line passing through thecenters of the valves, and Fig. 2 is a like view of the same upon a linepassing between said valves.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to increase the efiiciency and ease ofadjustment of pipeorgans; and it consists, principally, in the meansemployed for connecting together, operating, and relatively adjustingthe pivoted levers of the valves, substantially as is hereinafterspecified. It consists, further, in the means employed for closing thevalves and for regulating the pressure of the operatingsprings,substantially as is hereinafter shown.

In the annexed drawing, A represents the top, and B the bottom, of thewind-chest, divided, by means of suitable vertical partitions G, into anumber of compartments, 1). VVithin each partition (lis provided anumber of openings, E, which extend horizontally inward from one side toor near the center of said partition, from thence vertically upward tothe vertical center of the top A, and within the same horizontally tothe desired point, and thence upward, said openings being intended forthe passage of air from the windchest to the organ-pipes. Fitted overthe lower end of each opening E is a valve, F, that is secured to orupon one end of a lever, G, which lever projects downward through asuitable slot in the bottom B, and is pivoted to the latter at or nearits upper side, all in the usual manner.

As thus arranged, it will be seen that, by pressing the lower end of thepivoted lever G horizontally toward the partition against which itsvalve bears, said valve will be moved away from the latter, so as touncover the opening E, as seen in Fig. 1, while,,by

moving said pivoted levers in an opposite direction, said valve will becaused to close said opening once more, as shown in Fig. 2.

The pivoted levers of each series of valves are connected together bymeans of a threaded rod, H, which passes through the slotted end of eachin a line with its plane of motion, and is provided upon each side ofeach pivoted lever with a nut, h, that bears against the same, and, inconnection with the opposite nut, insures the relative positions of saidparts.

It will be seen that by moving the nuts longitudinally upon the rod thepositions of the valves with relation to each other can be easily andaccurately adjusted, so as to cause each to have a firm and perfectbearing upon its seat or partition.

The rod is sustained in position within the slotted ends of the pivotedlevers by means of a pin, g, that passes horizontally through the latterimmediately below said rod. The inner faces of the nuts h are madesemi-spherical so as to enable them to maintain their hearing withoutbinding as the relative angles of the pivoted levers and rod change. Oneend of each rod H is connected to or with one end of a lever, I, theopposite end of which is pivoted within a suitable bearing, K, attachedto one end of the Windchest. A half grasshopper spring, L, placedbetween the windchest and lever, presses the free end of the latteroutward and closes the valves.

In order that the tension of the spring L may be adjusted at will, astrip of wood, M, is placed between the end of the former and the innerface of the lever, and is secured in position by means of a stud, m,which projects from the face of said lever through a suitable slot insaid strip. A set-screw, N, passing through the lever L, bears againstthe end of the strip M outside of the spring, so that by turning saidscrew inward said strip will be caused to assume the position shown inFig. 1, and, by compressing said spring, increase its tension.

The improvements shown, while simple and inexpensive, materiallyincrease the efiiciency of an organ, and enable the necessary adjustments of the parts involved to be made with ease and dispatch.

the strip M, and the setscrew N, substantially as and for the purposeshown.

In testimony that I claim the foregoin I have hereunto set my hand. this2d day of J Line,
